The ITC said the decision would allow the automakers to transition to new suppliers for these programs.
LG Chem's wholly owned battery subsidiary, LG Energy Solution, an EV battery supplier to Tesla Inc. and General Motors, praised the ruling on Wednesday.
"SKI's total disregard of our warnings and intellectual property rights gave us no choice but to file this case," Kim Jong-hyun, the CEO of LG Energy Solution, said in a statement.
SK Innovation said on Wednesday it regretted the ITC's decision but noted there was a 60-day presidential review period in which President Joe Biden could decide to reverse the ruling. Biden has made EVs and reducing vehicle emissions a top priority. The White House declined to comment.
VW and Ford previously warned a U.S. legal row between South Korean battery makers could disrupt supplies of the key EV parts and cost U.S. jobs during the COVID-19 pandemic.
Farley said last week on a conference call with analysts that Ford's $22 billion investment in electrification does not include potential investment in battery production, whether through Ford itself or via a joint venture.
Georgia governor weighs in
Meanwhile, Georgia Gov. Brian Kemp on Friday called on Biden to overturn the trade ruling made against SK Innovation, saying the decision would hurt the EV battery maker's plant being built in Commerce, Ga.
"Unfortunately, the International Trade Commission’s recent ruling puts SK’s significant investment in 2,600 clean energy jobs and innovative manufacturing in peril during a pandemic," Kemp said in a statement.
Kemp warned that the long-term prospects for SK Innovation's $2.6 billion battery plant in Commerce would be "harmed significantly." The plant will eventually build batteries for Volkswagen and Ford.
White House officials could not immediately be reached to comment on Kemp's statement.
SK Innovation "can remedy this event by adequately compensating (LG Energy Solution) for their unlawful conduct," Song Jung, counsel for LE Chem unit LG Energy Solution (LGES), said in a statement. "LGES wants to work with Governor Kemp to help the plant and the workers, while upholding the rule of law.”
SK Innovation declined to comment on the governor's statement.
